What if Namco Bandai made another Pac-Man World sequel? I played Pac-Man World 2 to death on the Gamecube back when I was little (I think I was like 5 or 6 years old) and loved it so much, I literally cried when I beat it. Pac-Man World 3 was okay, but the level design was worse, the voice acting was annoying, and the combat was lame. If they make a Pac-Man World 4, I want them to make it follow in the footsteps of Pac-Man World 2. Maybe long ago during the "Pac-Ghost Wars" one of Pac-Man's ancestors, Sir Pac-A-Lot, defeated a traitor named Jagghoul (pronounced Jag-ool) who infused his body with a ghost, but was ultimately defeated. Then the Ghost Gang retrieves his soul from the Spirit Realm, then returning him to Pac-Land in his physical, non-transperent form. He and the Ghost Gang then plot to destroy the entire Pac-Land.
In this game, Pac-Man has to travel through 4 different time periods: Present Day, Middle Ages, Black-and-White Cartoon Days, and the Future, with his ancestors Sir Pac-A-Lot, Paceye the Sea Voyager (inspired by Popeye), and Starpac. Four player co-op is present and each character has unique abilities (Pac-Man can Butt-Bounce and Rev Roll, Sir Pac-A-Lot has Sword and Shield, Paceye can grow big and strong and use abilities like punch and kick and throws random objects like pianos and oil cans similar to characters in old-timey shows, and Starpac can use a Hoverboard and a Laser Gun). You travel through time multiple times in each level, so if it's impossible to go somewhere in a certain time, you use a time machine placed at convinient spots to progress through a level (similar to Sonic CD's time travel mechanic but easier and less annoying).
There are eight worlds: Grasslands, Underground Mines, Spoooky Woods, Wild West Canyon, Snowy Plains, Fantasy Land, Underwater Castles, and Jagghoul's Volcanic Lair, and a secret Pac-Labyrinth world. Each world has 5-7 levels and a Boss Level, and each level is more platforming based like Pac-Man World 2, and there are 2D sections and Power-Ups like Pac-Man World 3. What do you guys think?
I also had an idea where they could do a 2D platforming game where Ms. Pac-Man is kidnapped and Pac-Man and a Blue, Pink, and Green Pac-Man must save her, with 2.5D graphics and gameplay like Donkey Kong Country Returns and Rayman Origins, but with elements and ideas form the Pac-Man series, or an all-new 3D platforming Pac-Man game based off the television series (I like my Pac-Man World 4 idea the best though)
What do you guys think? Is this a good idea? Sorry it's so long...

I think Pac-Man seriously needs an amazing adventure game if they want people to like him again. All he's had since his new look have been party games and nobody truely cares about those all that much. I want a GOOD game with the new Pac-Man!

Also I really really REALLY want a Katamari game for Wii U.

I know not many other people like it but Pac Man 2: The New Adventures for SNES is one of my favorite Pac Man games. The music is catchy and the game is full of charm. They should re-release it on the Virtual Console. I could never get into to Pac Man World 2 on my Xbox though. Don't know why. Pac Man World for PSX looked more fun.
